  2. Conservation agriculture effects on plant nutrients and maize grain yield after four years of maize–winter cover crop rotations

    Conservation agriculture effects on plant nutrients and maize grain yield after four years of maize–winter cover crop rotations

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The effects of maize rotation with oat (Avena sativa cv. Sederberg) and grazing vetch (Vicia dasycarpa cv. Max) winter cover crops on nutrient availability, maize grain yield and maize grain nutrient concentration were investigated. Soil samples were collected from the...
